Hello. I have CCleaner loaded on a MacBook Air and after upgrading CCleaner, it is no longer deleting the Chrome history. The version of Chrome is 54.0.2840.87 (64-bit), the version of CCleaner is 1.14.451. The operating system is Mac OS X 10.11.6 (El Capitan). I've run the tool several times, always ensured Chrome was closed, and even rebooted, but still no luck. Any ideas? Thank you.
